Navistar RV Now Offers Cummins ISX15 Engine

Navistar RV, a subsidiary of Navistar International Corp., announced that it will now offer the Cummins ISX15 engine on certain recreational vehicle coaches. According to a press release, the new engine option is a result of an engine supply agreement signed recently between Navistar RV and distributor Cummins Crosspoint LLC.

“The ISX15 is one of the most popular heavy-duty engines in North America, and we are delighted to add it to our power portfolio,” said Bill Osborne, president, Navistar RV. “These big-bore engines will allow us to offer high-end diesel products with more horsepower, meaning we can introduce larger vehicles with unprecedented levels of luxury and performance.”

Highly adaptable to a wide variety of needs, the ISX15 is available for RV applications with 550 and 600 horsepower ratings and up to 1950 lb. ft. of torque. Its fuel system delivers maximum performance, regardless of engine RPMs, and multiple injection events improve fuel efficiency and enable a smoother, quieter ride. With a standard engine brake and impressive power, the ISX15 is a proven and compliant engine for RV usage.

The release of the first Navistar RV with the Cummins ISX15 engine is timed for dealer debut later this year.

“We had a limited amount of ISX engines that we used to build some previous Monaco coaches, and those were the best retail turns we’ve ever had in the field,” said Mike Snell, vice president sales, Navistar RV. “That reaction demonstrates a true sign of demand, and we expect our new ISX-powered vehicles to help us create a new level of high-end diesel units for the brand.”
